基于A-train卫星对中国北方地区气溶胶分布的研究

利用A-train(CALIPSO和MODIS-Aqua)卫星的数据资料,对比分析了中国北方地区(分为3个部分西部-W区,中部-M区和东部-E区)2007年1月~2010年10月AOD的年平均和季节平均分布特征,结果发现:MODIS-Aqua的卫星资料在我国北方地区区域基本具有适用性;MODIS和CALIPSO卫星反演的AOD年平均分布特征基本一致,AOD的高值区分布在南疆盆地(主要受沙尘气溶胶的影响)和地势较低的华北平原地区;MODIS和CALIPSO卫星反演的北方地区AOD季节平均分布的结果基本一致:W区AOD的高值区在季节上分布特征是:春季最高,夏季次之,秋季最小,冬季又慢慢增大;E区AOD的高值区的分布特征是:夏季最大,春季次之,秋冬季最小.

Research on the distribution of the northern region of China aerosol based on A-trian satellite

The A-train (CALIPSO and MODIS-Aqua) satellite data from January 2007 to October 2007 has been used in this paper to study the aerosol distribution characteristics of space and time on northern China (divided into three parts: the west region-W area, central region-M area, east area region-E). (1) The Aqua - MODIS satellite data can be better reflect the distribution of aerosols in north China region; (2) MODIS and CALIPSO satellite retrievaled the column aerosol optical depth distribution characteristics were basically the same, AOD high value area was distributed in W area-south xinjiang basin and low-lying plain of north China region; (3) MODIS and CALIPSO retrieval of aerosol optical depth distribution characteristics of northern China satellite were basically the same was: W areas AOD of the high value in seasonal distribution characteristic was: spring>summer>autumn, then winter increases slowly; E areas AOD of the high value in seasonal distribution characteristic was: summer>spring, followed by autumn and winter minimum.
